let current wind dance as moving streamlines on desktop background
the lua script wind_decode.lua downloads recent wind as json from
noaa (not yet), imports and decodes it and write to csv, to be
analysed by octave script wind_thread.m.
lua wind_decode.lua
the octave script wind_thread.m imports recent wind data from
wind.csv generated in (1), calculates some 10k streamlines from
random positions and saves them, seperated by "0 0" lines, as
streamlines.dat to be read by conkys lua script (3).
octave wind_thread.m
the lua script wind_weave.lua imports the streamlines from
streamlines.dat, and draws them using conkys cairo backend via
wind_blow.lua. This script is run automatically by (4), but has to
be changed to adjust opacity, linecolor, etc.
conky config script to load lua script wind_weave.lua, which prints the wind streamlines in streamlines.dat:
conky -c ~/wind/wind_blow.lua
- shell script: (1) and (2) need to be run once every time the noaa updates the wind data.
